Flight Duty Time does not start at the time you pitch up for work. You may grab a coffee... talk with collegues... what ever.
Your statement is entirely false. Crewmembers can put what ever time they want to put on the voyage report.
Just pitch up 45 minutes before flight. If the printers don't work... you can't get your flight plans... what ever the problem may be... note it on the voyage report.
If you have issues with alterations of time on a document take the matter up with your chief pilot.
